How to Fill Up the PART II – Computation of Tax of the BIR Form 1601C (Free Excel Template Download)

If you are a withholding agent with tax type BIR Form 1601C, you must withhold income taxes from your employees’ salaries.

But unfortunately many are still confused about how to do it wisely. The main reason why our fellow taxpayers are having a hard time is that they do not know how to compute the tax that must be withheld for BIR Form 1601C.

So in this short article, I will teach you how to compute the tax you should withhold from your employees in a very easy way.

By easy, I mean you don’t need to manually compute the tax because you will use an Excel template for it. You can download the excel template from the link at the end of this article.

Let’s dive into the actual process.

How to Compute the Income Taxes to be Withheld from the Employees’ Compensation?

Step 1: Prepare the Necessary Data to be Entered

In short, these are the data you must enter in the tax computation for BIR Form 1601C. Please refer below for the complete information needed.

  1. Complete name of your employees (First name and last name will suffice)
  2. TIN of your employee
  3. Basic pay or basic salary of your employee
  4. Overtime pay, holiday pay, nighshift differential, and hazard pay if any
  5. Absences and undertime
  6. Miscalculation adjustments or other adjustments
  7. Incentives if any
  8. 13th month pay
  9. De Minimis if any
  10. SSS employee deduction
  11. PhilHealth or PHIC employee deduction
  12. PagIbig or HDMF employee deduction

For this guide, let’s say I am filing for December 2021 with the following details of my employees.

TIN 222-222-222  333-333-333 
Basic Pay3,500.0025,000.00
OTP, HP, ND, and HP0.000.00
Absences and Undertime0.000.00
13th-month pay3,500.0025,000.00
De Minimis0.000.00
SSS employee deduction157.501,125.00
PHIC employee deduction150.00375.00
HDMF employee deduction70.00100.00

For easy demonstration, let’s say there is no overtime, holiday, nightshift differential, and hazard pay. Let’s say my employees also have no absences and undertime, adjustments, incentives, and de minimis.

But because the 13th-month pay is required to be paid every 24th day of December, they have a 13th-month pay equivalent to their one-month salary. To compute SSS, PagIbig, and PhilHealth, you can refer to the contributions table in the References section.
